INDIAN RIVER GENERATING STATION, an 804 MW Coal power plant in Sussex County, Delaware. Operated by INDIAN RIVER OPERATIONS INC, commissioned 1967.
How INDIAN RIVER GENERATING STATION compares
With 804 MW of capacity, INDIAN RIVER GENERATING STATION ranks 2nd among the 22 operating power plants Bywatts maps in Delaware and is the largest of the 3 operating Coal plants in the state. It accounts for about 49% of Delaware's operating Coal capacity and 23% of all operating capacity in the state. Nationally it is the 126th-largest of the 324 operating Coal plants in the database. Commissioned in 1967, it is older than 80% of the 21 operating Delaware plants with a recorded commissioning year. It shares Sussex County with 5 other operating plants, including AMERESCO DELAWARE SOUTH and UNIVERSITY OF DELAWARE WIND TURBINE.
EIA-860 lists 2 generators at the site with 464 MW of nameplate capacity, mainly conventional steam coal technology (this page's HIFLD capacity figure is 804 MW). Net generation was 148 GWh in 2024 (a 3.6% capacity factor). Its generators came online between 1967 and 1980.
